SMOKE-CONVEYER.

SPECIFICATION forming part of Letters Patent No. 663,91 7, dated December 1S, 1900.

Application filed May 24, 1900.

To all whom, if; may concern,-

Be it known that we, GALT M. MEINEN, JOHN` H. GROVE, JOSEPH J. Lin'rsoH, and THEOPHILUS L.MnLvEN,citizens ofthe United States, residing at Louisville, in the county ofi Jeiferson and State of Kentucky, have inventeda new and useful Smoke-Oonveyer,of which the following is a specification.

Our invention relates to a novel smoke-conveyer designed particularly for use in connection with railroad-trains.

One object in view is to provide a conductor or conveyer which will receive the smoke and.A gases from the stack of alocomotive and discharge them at the rear end of the train, the purpose of the device being to prevent the smoke and cinders from coming into contact with the cars to the annoyance of the passengers and the soiling of the car furnishings and finish.

A subordinate object is tO provide for the unrestricted direct escape of the smoke from the top of the stack when the locomotive is at a standstill by means of a cap or valve 1ocated and arranged in a manner to permit its direct escape or to close the top of the stack in a manner to compel the smoke to pass therefrom into the conveyer and to admit a direct draft through said conveyer for the purpose of carrying the products of combustion therethrough.

To the accomplishment of these several objects the invention consists in the consi ruction and arrangement of parts to be hereinafter described and illustrated,and succinctly defined in the appended claims.

In the accompanying drawings, Figure lis an elevation of a locomotive equipped with our smoke-conveyer. Fig. 2 is a fragmentary perspective view of the contiguous portions of the conveyer and stack, showing the cap Open and illustrating its closed position in dotted lines.

Referring to the numerals of reference employed to designate corresponding parts in the several views, l indicates a locomotive, and 2 a tender, coupled together in the Vordinary manner and comprising a railway-train.

4 indicates the smoke-stack of a locomotive, and 5 a tubular smoke-conveyer, preferably of about the same diameter as the stack and Serial No. 17,876. KNO model.)

extending rearwardly from the upper end of the stack to the rear end of the train, where the products of combustion from the furnace of the engine are designed to be discharged. The conveyer 5 is made up of a number of iudividual sections, one of which is preferably supported upon each vehicle by conveyer-supporting brackets 6, comprising a ring 7, encircling the conveyer-section adjacent to its 6o ends, and a pair of legs or standards 8, supporting the ring 7 and bolted or Otherwise secured to the top of the vehicle. Suitable means for coupling the several conveyer-sections are necessarily employed, as shown.

At suitable points along the conveyer and preferably in each of the sections is provided a draft or Ventilating opening 16, straddled by an angular ventilator 17, arranged to permit the ingress of a current of air serving to 7o 'aid in the propulsion of the products of com- Vucts through the ventilator-Opening.

The essential feature of our invention is that arrangement at the juncture of the conveyer and smoke-stack which permits the direct escape of the smoke and-gases from the latter under certain conditions and compels such products of combustion to be discharged 8o into and through the conveyer under certain other conditions.

In Figs. land 2 of the drawings it will be seen that the front end of the conveyer-that is to say, that section which is carried by the locomotive-is bent at right angles to form a thimble or sleeve 20, which is slipped over the upper end of the stack 4 to have a smoketight connection therewith. The upper front corner of the conveyer is cut away at an an- 9o gle of about forty-ve degrees to form an opening 2l, disposed angularly with respect to both the stack and conveyer and coeXtensive diametrically with both the stack and conveyer, so that when this opening is unobstructed the front end of the conveyer and the upper end of the stack will be entirely open. The purpose of this peculiar arrangement is to provide for the direct escape of the smoke and gases from the stack I when loo the locomotive is at a standstill and the Opening 2l is uncovered. Under ordinary conditions, however-thatis to say, when-the train is in motion-this'open'ing 21 m'ustbe' closed to prevent the exhaust from driving the smoke and cind'ers upwardly through the opening and into contact with the cars. For this purpose we provide-a cap or valve22, preferably of'convexl circular form and hinged, as b v'a` hinge 23, to the sleeve 20 of'v the conveyer at the lower edge of the opening 2l.

Suitable means for actuatingv the capfor valve 22 and for retaining it in its opened and closed positions must be provided, and we prefer to employ a capactuatingrod 24, pivotally connected to the cap and extended rearwardly into the cab of the locomotive; within convenient reach of the engineer. order to create a'direct draft throughith'e con veyer when the train is in motion, weprovide' the cap with an opening 25, locatediinapo; sition to be coaxialwith the couveyer whenl the cap'22 is closed, and from' this opening:A

We extend a draft-funnelv2, Whichwhen theV cap is in its incliuedclosed position will: be:

disposed coaxially with theconveyer. 'lhus by the manipulation of the cap `or valve 22 we are enabled to provide a direct openingat t'he upper end of the stack for the escape of the products of combustion or to completely close theupp'er end' of the stack and toinffruguratev a draft through the conveyer ,from a' point loi cated beyond the frontofy the stack for the purpose of compelling the smoke and gases to be projected through the couveyer anddischarged at the rear ofv the train?.A

From the foregoing it will be observedithat we have produced af simple, ingenious, and

elective arrangement for discharging the product's'of combustion from there-box of a locomotive at the rear of the train'x to'pre- Vent annoyance tothe passengers and damage lo thefinish and furnishings of the cars; but while the present embodiment of our in:- ven-tion appears at this' timeto be preferable we'dofnot desire to limit ourselves to the details" dened', inasmuch as various changes, modifications,- and: variations might be ef- InU 'both the stack and conveyer, a hinged cap arranged to close:over1tlie' openingyafdraft-l funnelopening. through' the cap-at? a point coaxial with: the conveyer whenthe cap'- is closed'and disposedaatr an'angletoithe'cap to permit such coaxialrelationfand means for actuating the cap.
